Detroit Diesel Alpine Green Engine Paint 12oz

Detroit Diesel Alpine Green Engine Paint is purpose-built for restoring and customizing Detroit Diesel engine blocks with the iconic factory Alpine Green finish. Whether you're rebuilding a classic Detroit 2-stroke, freshening up a 6V-92 or 8V-92 power plant, or matching original equipment manufacturer colors on a vintage truck engine, this 12oz aerosol spray delivers authentic OEM-spec color reproduction. Mechanics and diesel enthusiasts trust this formulation because it's engineered specifically for high-heat engine compartments and the demanding environment of fuel-injected diesel powerplants.

The spray formula uses DUPLI-COLOR/KRYLON's enamel-based technology, which bonds directly to cast iron and aluminum engine blocks without primer on properly prepared surfaces. Alpine Green requires minimal surface prep—light sanding or wire-brushing to remove rust and loose paint is sufficient—and cures to a durable, semi-gloss finish that resists oil saturation and thermal cycling. The 12oz can delivers consistent atomization from first spray to last, allowing mechanics to achieve factory-smooth coverage on heads, blocks, and manifolds in a single session without runs or thin spots. Heat resistance to 500°F ensures the finish won't fade, crack, or peel under normal operating temperatures.

This paint is ideal for Detroit Diesel engine restorations, marine and industrial diesel engine overhauls, and vintage truck builds where original color matching is essential for authenticity and resale value. The aerosol format makes it perfect for detail work around sensor bosses, oil galleries, and tight engine bay spaces where brush or roller application would be impractical. Application temperature range of 50–85°F ensures reliable performance across most shop environments. One 12oz can covers approximately 8–10 square feet depending on engine surface texture; most complete engine block jobs require 2–3 cans for full coverage with proper opacity.
